Abstrac tThe genus Geronth aWalker ,1864 is recorded frQm Hainan Islan dC,hina for the first
time. Gerontha "ex"r sap. nov, is described and illustrat edT.he new species ca] be distinguished
from other Geronth aspecies by the slender aedeagus which i scurvcd ventrally near the apex and
the spindle-shapcd precess arising from dorso-proximal base of valva.

Introdllction
The genus Geivntha was established by Walker in 1864 with Ge]z,nth acaptiosella XNTalket,
1864 as type species, and redescribed thoroughly by Diakonoff (1968 ).Twenty-two nomi-
nal species are hithert oincluded in this genus (Meyric k1,928; Diakonoff, 1968; Zagulajev,
1972; Moriuti,1977, l989a, b;Petersen,1987;Robinson& Tuck,1996;Ponomarenko&

Park, 1996), and excepting G. acrosthenia Zagulaje vfrom New Guinea (Zagula j1e9v7,2)
and Australia (Robinso n& Nielsen ,1993) ,almost all the species are knewn from the
Orienta lRegion to East Asia. In China, Gervntha hoenei Petersen ,1987 was reported from
YUnnan and Zhejian gProvinces, and G, dracuncul aMeyrick, 1928 from Taiwan. Up to the
present ,no Gerontha species have been recorded from Hainan Island , One Geivntha
species collected in our survey of Lepidoptera in Hainan lsland was considered to be new to
science, The terminology used in descriptio nofs morphology follow sRobinson & Nielsen
(1993).

Etymology. From the Latin (=bendin gre)ferring to the aedeagus which is nearly

straight and curved ventrally near the apex.
Remarks, Gerontha in
species are often very closely similar superficial appearance and
separation is sometimes extremely diracul etven based on the genita lcharacters, The new
species is similar to G. dracuncul aMeyrick, 1928 from India (Andaman Islands) and G,
amplipteiu Ponomarenko & Park, 1996 from Korea in having a simple uncus not produced
into paire dlobes and a gnathos which is very weakly sclerotized or absent in the male geni-
talia. Judging from the characters of the valva with a small process at the middle of the
